    Towards Multimodal Simultaneous Neural Machine Translation

    Full text link
    Simultaneous translation involves translating a sentence before the speaker's utterance is completed in order to realize real-time understanding in multiple languages. This task is significantly harder than the general full sentence translation because of the shortage of input information during decoding. To alleviate this shortage, we propose multimodal simultaneous neural machine translation (MSNMT) which leverages visual information as an additional modality. Although the usefulness of images as an additional modality is moderate for full sentence translation, we verified, for the first time, its importance for simultaneous translation. Our experiments with the Multi30k dataset showed that MSNMT in a simultaneous setting significantly outperforms its text-only counterpart in situations where 5 or fewer input tokens are needed to begin translation. We then verified the importance of visual information during decoding by (a) performing an adversarial evaluation of MSNMT where we studied how models behave with incongruent input modality and (b) analyzing the image attention

    M3P: Learning Universal Representations via Multitask Multilingual Multimodal Pre-training

    Full text link
    We present M3P, a Multitask Multilingual Multimodal Pre-trained model that combines multilingual pre-training and multimodal pre-training into a unified framework via multitask pre-training. Our goal is to learn universal representations that can map objects occurred in different modalities or texts expressed in different languages into a common semantic space. In addition, to explicitly encourage fine-grained alignment between images and non-English languages, we also propose Multimodal Code-switched Training (MCT) to combine monolingual pre-training and multimodal pre-training via a code-switch strategy. Experiments are performed on the multilingual image retrieval task across two benchmark datasets, including MSCOCO and Multi30K. M3P can achieve comparable results for English and new state-of-the-art results for non-English languages.Comment: Accepted to CVPR 202
